Title: Clock signal buffering device
Inventor: KIM MIN-HWAN
IPC: H03K19/00
Filed: 1992-12-28
Granted: 1995-03-10
Abstract: The circuit for buffering clock signals to constantly maintain the duty ratio of clock signals, in cludes an input line (30) for inputting clock signals to be buffered, a comparator (30) for comparing the clock signal from the input line (32) with a reference signal to generate a buffered clock signal of a logic state varied by the result, and a feedback loop circuit (34,36) for generating the reference voltage of a varied voltage level according to the duty ratio of the buffered clock signal from the comparator (32). The feedback loop circuit includes an integrator and a dc level shifter.

Title: Wavy louvered fin-tube typed heat-exchanger
Inventor: RYU HO-SON
IPC: F28F1/32
Filed: 1993-04-16
Granted: 1995-03-20
Abstract: The heat-exchanger for improving heat transfer efficiency, has a two-stepped pin plate structure. The heat exchanger has a wavy louvered type fin plate with primary fin plate section and secondary fin plate section having a cirtain curved angle (θ5) against the primary fin plate section (-45<=θ5<=45). The primary fin plate has a surface with a certain roughness (R) and the secondary fin plate has a smooth surface. The roughness (R) is bigger than zero and less than a tenth of distance (h1) between upper and lower plates (0.1 h1).
